Subscript & superscript equation
显示 更早的评论
cannot manage to add the equation in the mention capture shoot image at the matlab !!!
Tried to use the same sequence mention in https://www.mathworks.com/help/symbolic/add-suffixes-to-symbolic-results.html
but didn't work !!!
Tried latex and it gives another answer than it should become.
Kindly need an assistance in that concern !!!

You need to use latex in the equation editor, not symbolic.
This expression x1=x_{b_1}^{a_1} turns into this:
Note that MATLAB only supports a subset of the latex libraries. If you need help building your equation, you can do so interactively in a live script using the equation editor.

You can also use \frac if you want. This:
\parallel\upsilon^c_n\parallel=\frac{\parallel{P^c_{n+1}-P^c_n}\parallel /}{\Delta} \leq \upsilon_{max}
becomes this:
The Equation Editor creates the expression using slighly different syntax:
\left\|\upsilon_n^c \right\|=\frac{\left\|P_{n+1}^c -P_n^c \right\|}{\Delta }\le \upsilon_{\max}
Once created, you can rt-click on your equation and select 'Copy as latex" if you need to insert the equation elsewhere.

Try it out and see if it displays correctly. As a hint, you can enclose it in dollar signs to turn it into an equation here in the editor.
$E_{O,k,n}^d(L_{k,n}^d,P_n^c)={\frac{{N_oB\frac{\Delta}{K}}}{g_{k,n}{(P_n^c)}}\times{(2^{\frac{L_{k,n}^d}{B\frac{\Delta}{K}} -{1})$
becomes

$E_{O,k,n}^d(L_{k,n}^d,P_n^c)={\frac{{N_oB\frac{\Delta}{K}}}{g_{k,n}{(P_n^c)}} (2^{\frac{L_{k,n}^d}{B\frac{\Delta}{K}}} -1)$
I got it
it was a missing bracket in wrong place ........
Thank you Cris LaPierre

That works, though with some tweaks you can get it to look better.
$E_{O,k,n}^d \left(L_{k,n}^d ,P_n^c \right)=\frac{N_0 B\Delta /K}{g_{k,n} \left(P_n^c \right)}\left(2\frac{L_{k,n}^d }{B\Delta /K}-1\right)$

S = "m\frac{\partial^2}{\partial t^2}=mg - ky";
symstr = ["'The equation of motion is'"; S;"'where k is the elastic coefficient.'"];
displayFormula(symstr)
doesnot display like that
The equation of motion is
where k is the elastic coefficient.
I dont know why!?
In your ded.jpg image, you were trying to use the Edit Equation tool to create your equations, so that is how I've shown you how to create equations.
In your latest question, it doesn't work because displayFormula is for displaying symbolic equations, not latex equations. Follow this example from the displayFormulat documentation page.
S = "m*diff(y,t,t) == m*g-k*y";
symstr = ["'The equation of motion is'"; S;"'where k is the elastic coefficient.'"];
displayFormula(symstr)
